Question

this series of problems will build your fluency with classifying associative trends. for each question below, name the association and its strength.

• use the answer key to determine that you accurately labeled each scatter plot.
• if necessary, revise your work.

label each graph with its association and strength.
1.
scatter plots labeled a, b, c, d, e, f, g are shown, with a, b, d, e, f having apparent linear trends and c, g having more scattered or no clear trends

Explanation:

To solve this, we analyze each scatter plot for direction (positive/negative) and strength (strong/moderate/weak/no association):

Graph A

• Association: Positive (as x increases, y increases).
• Strength: Strong (points lie very close to a straight line).

Graph B

• Association: Positive (x and y increase together).
• Strength: Moderate (points follow a trend but with slight scatter).

Graph C

• Association: Positive (upward trend).
• Strength: Weak (points show a trend but are more scattered).

Graph D

• Association: Negative (as x increases, y decreases).
• Strength: Strong (points lie close to a straight line).

Graph E

• Association: Negative (x increases, y decreases).
• Strength: Moderate (trend is clear but with some scatter).

Graph F

• Association: Negative (downward trend).
• Strength: Weak (points are scattered but show a trend).

Graph G

• Association: No association (points are randomly scattered, no clear trend).
• Strength: No association (or "weak" in the context of no trend).

Final Answers (per graph):

• A: Positive, Strong
• B: Positive, Moderate
• C: Positive, Weak
• D: Negative, Strong
• E: Negative, Moderate
• F: Negative, Weak
• G: No Association, No Strength (or "Weak" for no trend)

• Strength: No association (or "weak" in the context of no trend).

Final Answers (per graph):

• A: Positive, Strong
• B: Positive, Moderate
• C: Positive, Weak
• D: Negative, Strong
• E: Negative, Moderate
• F: Negative, Weak
• G: No Association, No Strength (or "Weak" for no trend)
